Who up playing with their orb
I dunno what it is, I've always loved games where you roll a ball around. marble blast, marble it up, MONKEY BALL THE GOAT! Something about them just hit different, and I can see the influence here super clearly. While I think you have a great start, there is some missing oomph that I think you could add to make the game really shine.
Big thing, I couldn't move the camera on keyboard, and I could only move the camera with a controller. Unless I messed something up (Very real possibility, mind you) I couldn't find a controller configuration that DIDNT block me from using a certain aspect of the controls. Beyond that, I feel like the game was lacking in the sound department. having even just a sound for when the ball is rolling normally would do wonders for the game feel and really tie things together. I feel the ball moved pretty responsively and had a pretty solid feel and weight to it, which made navigating feel pretty good, which is honestly the hardest and most important part to get right. Seeing how the scene is static, the skill ceiling is pretty low, which makes it sort of a hard sell as an arcade experience. I think maybe a bigger, perhaps procedural course might make things a bit more spontaneous and lend to that arcade-y feel more? Just spitballing at this point.
Anyway, you have a great start here! If you iron out some of the kinks, you'll have something even cooler!
